SPECIFICATION forming part of Letters Patent No. 652,772, dafd T 111e'3, 190@ A Application filed February 4, 1898. Serial No. 669,070. (Nomodel.)

To au whom it. may concern:

Be it known that we, WILLIAM HINDLEY,

of Hoboken, in the county of Hudson and' State of New Jersey, and JOSEPHWM. HARD- ING, of New York, (Brooklym) in the county of Kings and Stateof New York, have invented certain new and useful Improvements inWood-Sawing Machines, of which the following is a full, clear, and exactdescription. This invention relates to improvements 'in wood-sawingmachines, but more particularly to machines for sawing kindling-wood.

The primaryy object of the invention is to` provide a simple andefficient machine adapted to receive long bundles of wood bound atstated intervals, which will carry the bundles forward, and which willhold and cut the bun-v forming a part of this specification, whereinsimilar figures of reference designate similar parts, Figure 1 is a sideelevation of one form of the machine embodying our invention. Fig. 2 isa sectional plan View, partly broken away, taken on the line II II ofFig. 1. Fig. 3 is a vertical transverse section, partly broken away,taken on the line IIIIII of Fig. 2. Fig. 4 is a fragmentary longitudinalvertical section taken on the line IV IV of Fig. 3, and Fig. 5 is afragmentary detail view illustrating means for imparting a verticalmovement to the saws.

The frame may be of any desired form and may consist of lsections 10 and10?, suitably bolted and secured together, in the former of which arejournaled the transverse'shafts 11 and 12. On each of these transverseshafts is secured a drum 13, provided at intervals with sprocket-teethwhich engage the links of the endless chains or carriers 14, thoughinsteadof thel drums a series of sprocket- 4wheels may be employedcorresponding in number to the number of endless chainsror carriers withwhich they engage. On the .chains14 and arranged at stated intervals arebuckets or jaws 15, which maybe secured to or formed as a part of one oftheJ connectwith the gear 17 is a ratchet-wheel 19, normally engaged bya spring-pressed pawl 20, pivoted to the arm 21, the latter having oneend journaled loosely on the shaft or stud 1S and its other end providedwith a stud or pin 21a, on which maybe arranged a roller normally inengagement with the grooved cam 22. This cam 22 is secured to the .shaft23, on which may be arranged a drive-pulley 24, so that when the latteris rotated thecam 22 will rock the arm 2l on its pivotand through thepawl-,and-ratchet andjgear mechanism already described will impartanintermittent movement to the drums 13 and the endless chains orcarriers 14, so as to carry the bundles of lwood forward the distancebetween any two series of jaws or buckets 15 at each revolution of saidcam. Y

The bundles of wood 15a as they aredropped into the buckets 15 assumethe position shown to the right in Fig. 1, and as thechains 14 andbuckets 15 are advanced the Ywood will contact lwith a suitable engagingdevice. As

- shown, this device comprises .a series of rollers 25, which arearranged to rotate'with the transverse shaft 26 (shown in- Figs.j1' and2) in order that the bundles of wood when'engaged by the rollers maybeforced or rocked so as to assume the position shown in full lines inFig. 4. For the purpose of holding the bundles while being cut orseparated we may provide a movable head or clamping device IOC 27,arranged to slide in the sections l0 of' the frame, and on the underside of said head, between the sections of the frame are arranged aseries ot clamping-jaws or buckets 28, corresponding in form to thebuckets- These jaws 28 have their con-y caved portions opposed to theconcaved porl tions of the buckets 15, so as to snbstantially surroundthe bundle when the latter is or jaws 15.

tions 10a of the frame and have their upper. ends pivoted to rock-levers32, the latter having one end thereof connected to the links 33, pivotedto the sections of the frame, and

their other ends connected to verticallymovable connecting rods 34.

arms or levers 35, secured `to the transverse shaft 36, one of said armsbeing .extended so j as ,to form a bell-crank lever and provided at itsupper end with a roller 36, which nor-A mally engages a cam-groove inthe cam 37, which is .secured toa stud or shaft 38. 0n

the shaft 38 `is Varranged a gear 39, which meshes with an idler 40 onthe shaft 12,1V which in turn meshes with an idler 4l, the i latterbeing in mesh with the gear 42, se cured to the drive-shaft 23, so thatv.when the latter 'is rotated the trai-n of gearing will impart a rotarymovement to the shaft 38. This shaft 38 is properly timed with respect.to the intermittentmovementof the sprocketrotated said shaft,' throughthe .cam 37, roller 36, arms `35, lcon,` necting-,rods 34, and itsconnections, will impart a vertical movement to the .clamping- A seriesof grate-bars 43 are arranged below ,the head 27, forming a stationarybed over which the chains 14 are adaptedl to pass in order to formasupport for the. chains carrying the buckets or yjaws when theclamping-head-27 is forced downward to 1 hold the bundle of wood. Thesegrate-bars may be secured to -T-shaped 4cross-' bars, aSi

drums 13, and when head 27.

44, secured to the sections 10 of the frame,

though instead of the grate-bars any suitable bed may be provided.

These saws are separated by suitable collars back and forth in thesections 10 of the frame, and the shaft 46 is connected to the links 50,the outer or forward ends of which These arms are secured to thetransverse shaft 51u, one of. which arms is connected by a rod 52 to arockare pivoted to the arms 5l.

These connecting-rods have their lowerends pivot-ed to arm 53, looselyarranged upon the transverse shaft 36.. This arm 53 may have a suitableroller which engages a cam-groove in the cam 54, the latter beingsecured to the shaft 38, so as to rotate with the cam 37. By this meansthe saws are moved inwardly toward the clamping-head 27, so as to dividethe long bundle into independent smaller bundles or packages 151.

The saws 45 may be rotated in any desired manner. As shown, the shaft 46has a pulley 55 at oneend thereof, around which passes a belt 56, whichis rotated by the pulley 57, the latter being suspended by movable links58, arranged on the shaft 59. The links 58 are connected to the shaft 46by the connecting-rod 60, so that the shafts of the pulleys 57 and 55will remain .a fixed dist-ance apart. To the shaft Aot the pulley 57 issecured a pulley 61, which is rotated yby a belt `62 which passes around,the pulley 63, arranged .0n .the shaft 59, the latter shaft beingsuitably suspcnded and rotated by means of Hthe drivepulley 64. Thearrangement `o t' the links 58 permits the sha-ft 46 `to be constantlyrotated while being moved lengthwise of the machine.

vThe operation of the invention will be readily understood from theforegoing description when taken in connection with thc ,accompanyin gdrawings.

The bundles .of wood being deposited in ,the buckets or `jaws 15 in .anysuitable manner and the pulley 4,2 rotated, it will be seen that the cam22 will rock the arm 2l on its pivot, and through the pawl 20ratchet-wheel 19, gear 17, and pinion 1=6 .anintermittent movement willbe imparted tothe shaft 12,7 drums, and endless chains 14, thusadvancing the bundles in the buckets or jaws. As the chains .advance`the bundles contact with ,the rollers 25 on the transvers shaft 26 s0vas to be forced to the position shown in Fig. 4. This intermittentmovement continues until one series of buckets are in alinement with theclamping -head 27 yThe head is now moved downward 'by the rods 30,levers 32, connectingrods 34, arms 35, and cam 37, which latter isrotated by the train of gearing from the shaft 23, as hereinbeforedescribed. Vhile ,the bundle is clamped between the jaws 15 of thechain, which is supl ported by the 4{.*rate-bars of the bed and .the Thesaws 45 may be 0f any desired number I and are varran ged on thetransverse ,shaft 46.

jaws 28 of the clamping-head 27, the saws 45, which are rotated by thedriving lmechanism heretofore referred to, are moved inwardly toward thehead to the position shown in the drawings by the links 50, arms 51,connecting-rod 52, rock-arm 53, and cam 54, thus separating the bundleof Wood into a number of smaller and independent packages. The

:clamping-head 27 is now raised by the mechanism already described. Thesaws 45,

ICO

ously with the outward movement of the arms 45 the drums 13 and chains14 are given an intermittent movement, so as to place the next bundle inposition for the clamping-head to engage and rigidly hold the same forthe next inward movement of the saws 45. The operation is repeated, andthe divided bundles are carried outward by the carriers or chains, and,as the buckets rotate around the drum on the shaft 1l, may be removed orthey will be dropped on the floor, as shown in Fig. 1, or into asuitable receptacle provided therefor, as desired.

We thus provide an efficient machine which will carry the long boundbundles of wood forward, hold and cut the same between the bindingsready for the market, and after being cut the smaller bundles will becarried outwardly, so as to be readily removed or dropped into asuitable receptacle provided therefor.

While we have described mechanism for intermittently moving the carriersor chains as a part of the machine, we may arrange said or similarmechanisln on a suitable bundlingmachine, such as described in ourpending application, Serial No. 658,256, iiled November 12, 1897. Whenused in this manner, the chains or carriers are arranged so that thelong bundles of wood when bound will drop from the binding mechanismdirectly into the buckets or jaws 15.

In some instances it may be found desirable to move the saws verticallyinstead of horizontally, as shown in Figs. 1 to 3, inclusive. In suchcase the saws may be suspended from an oscillatory lever or arranged asshown in Fig. 5. Here the shaft Li6 is journaled in the cross-heads 65,which are vertically movable in the sections 10 of the frame and areconnected to the links 66, only one section of the frame and theconnecting parts being shown. The links 66 are connected at one end tolevers 67, one of which connects to a rod 68, the latter being operatedin a similar manner to the rod 52, (shown in the other figures,) so thatas the levers 67 are rocked on their pivots the saws,throu gh thelinks66,will be given a vertical movement. When thus arranged, the saws maybecarried away from the path of movement of the bundles after the samehave been cut and before the clamping head or device 27 is released.

It will be readily seen that other clamping means than the head may beemployed, that any desired form or construction of saw or saws may beused, and that some of the parts may be dispensed with or otherssubstituted therefor without departing from the spirit of our invention.

Having thus described our invention, we claim as new and desire tosecure by Letters Patenta second series of vertically-movable jaws alsoshaped to fit the stock and adapted to close over the same when thetraveling jaws are at rest, and a series of rotatable saws movablebetween the jaws and in the path of the stock, substantially asdescribed.

2. A wood-sawing machine, comprising a series of intermittingly-movablechains, each having buckets or jaws at stated intervals thereon, thesaid jaws being shaped to iit the stock and arranged with the jaws ofone series parallel with those of adjacent series of chains, verticallymovable and similarlyshaped jaws adapted to close over the stockopposite one of the traveling series of jaws when the latter are atrest, and a gang of rotary saws arranged in the path of the stock andbetween the series of jaws, substantially as described.
